Leila / Layla - quite like it. I think they're in a bit of a homogeneous lump witha a lot of other similar sounding names but they're pretty.
Amber - like it. Prerry and not overly popular.
Hazel - quite like it. And quite unusual for a child now, I think.
Lois - like it. Used to really dislike it but it seems elegant and cool at the same time to me now.
Sabrina - not keen. I can't not add 'the teenage witch' to the end but I suppose kuda now wouldn't do that.
Jasmine - ambivalent. It's a pretty name.
Alma - not keen. Seems a bit old lady. I don't think it's made the transition in the same way a lot of names from that generation have.
Merryn - like it. Unusual and pretty.
